All good points about fear ruling your life, but I totaly agree with you - when you have to support yourself, you need a good plan and a backup... and motivation to get you through. My concern for you is that job jumping right now may not solve anything as you are discontent and trying to move away from it. I think you need something new to draw you in and pull you away from your job instead if that makes any sense. Give yoursealf a chance to slog through the sludge right now until you can really figure this out. I am sure you will - mainly because you are taking action. Taking classes, meeting people, working with the horses - these things are all working on you - changing you.
Also, if you are not taking D3, I'm sure you are low. Even in a sunny place like CO, we need more D3 supps. I take 5000IU daily (sometimes more) and so does my hubby and our levels are in the lower good range. I never felt a huge diff from it, but many have.
Glad to hear you got some good sleep last night. I love wine also, but it can really mess up my sleep too.
